Fixed Splitting, Increased Aortic Intensity S2 Lesson
The patient was sitting during auscultation.
Description
Listen to this recording of a second heart sound with fixed splitting and including an increased sound intensity of the aortic component. This condition is seen in some patients with chronic, severe hypertension; aortic pressure is significantly increased.
Our recording contains fixed splitting of S2 to make it easier to concentrate on the relative intensities of the aortic and pulmonic components. In the cardiac animation video, note the increased thickness of the left ventricular wall caused by essential hypertension.
